de Young Museum - Foundation Stabilization

The de Young Museum in San Francisco, California, required the construction of soil-cement columns and installation of soldier piles as the foundation for shoring walls used during construction. Some of the columns were to remain after building construction as an additional soil stabilization feature. The soil-cement column elements were expected to resist ground movement in shear, and steel pile inserts were incorporated to provide a high level of assurance of column continuity, strength and “ductility” in shear.

Scope of Services:

ADH provided observation of installation activities and representative sampling for the construction of 57 30-inch diameter soil cement columns to depths up to 60-feet below ground surface as part of a foundation stabilization program located at the de Young Museum in San Francisco, California. Observation and reporting procedures were performed in accordance with the requirements specified by Rutherford & Chekene.
